The top two players are on collision course to meet in the final of the Barclays ATP World Tour Finals at The O2.

The Scot ended the Serb's 122-week reign as No 1 last week but will return to the top of the rankings by claimning his fifth consecutive title at The O2.

Djokovic has a winning 24-10 record against Murray, including victory in their last meeting in the French Open final in June.

And McEnroe told the BBC: “Novak still has a decided edge in the bigger matches and is much better head-to-head so it would lead me to believe that if they walk on the court on Sunday for the final, he would have a real chance to get things right in his mind and finish the year as No 1.

“But Murray has obviously done a lot of good things to get to this place and has been playing the best overall the last six months. So if there was a time where he was: 'Alright, I am ready to finally make this step', it would be a hell of a place to do it.

“He has been extremely patience, perservered and got better. That for me makes this match-up even more interesting. That is why I hope, either in the final or the semis, that they play.”
